China Jfa302 China Water Quality Tester Digital Online Conductivity Meter

Description:
Conductivity indicate the electric performance of substance. The bigger conductivity, the bigger electric performance.
The main materials of conductivity is black polypropylene shell and glass-platinum electrode, almost suitable for all occasion.
The structure is so firm and with good durability, which can be operated in many test locations with bad conditions.
Transmitter is apply in displaying the data measured by conductivity sensor. Users can set and calibrate the interface of transmitter
to make 4-20mA analog output, the function of relay control and digital communication can be achieved.
Measure principle.
Electric conductivity sensor is made of glass-platinum electrode. The measure principle of instrument,
put two disc(electrical conductivity patch) in the sample solution, and then add a voltage in the disc,
the current will be measured. Generally, voltage is sine wave form. Conductivity is determined by Ohm formula
according to voltage and current value.
Features:
Favorable repeatability and stability.
Easy to clean and activate, with fast balance speed.
Anti -temperature compensation function.
Equipped with analog to digital conversion to realize digital signal output.
Strong anti-interference and far transmit distance.
Equipped with analog to digital conversion to realize standard digital signal output(RS485),
which can make a integration and networking with other equipment under the no controller.
Convenient to install sensor at the site, plug and play.
Concise usage, reliable result. Interface operation instrument can reduce failure.
Vital warning function provided by visual alert system.
Controller can be installed in wall mount, panel mount and pipe clamping.
